onsemi Announces Sungrow Deployment Of Its Latest Elitesic Silicon Carbide Hybrid Power Module Technology

onsemi (NASDAQ:ON) today announced that Sungrow, a global leader in renewable energy technology, has adopted onsemi’s latest EliteSiC silicon carbide (SiC) hybrid power module technology for the Sungrow PowerTitan 3.0 energy storage platform. The integration enables improved efficiency and enhanced system performance for utility-scale battery energy storage systems (BESS).

Helping Sungrow Deliver More Usable Energy

The PowerTitan 3.0 platform incorporates onsemi’s high-density power integrated modules (PIMs), optimized for advanced three-level inverter architectures used in high-power energy storage applications.

Compared with the previous-generation platform, the new architecture improves inverter-level efficiency by 0.4%, enabling higher-power battery storage deployments without sacrificing efficiency. The architecture supports power conversion units rated up to 450 kW, contributing to the platform’s increased power density and higher-power deployment capability.

With the performance advantages of SiC, the solution supports key system-level benefits including:

Peak efficiency exceeding 99.3% to reduce energy loss in utility-scale systems
Increased power density supports higher-power BESS deployments
Enhanced thermal performance supports reliable operation in high-power applications
Improved system economics through a hybrid SiC design optimized for large-scale deployment
The design win builds on a long-standing strategic relationship between onsemi and Sungrow. Through extensive engineering and validation activities, the companies collaborated throughout platform definition, system optimization and qualification to meet the demanding performance requirements of next-generation energy storage deployments.
